NASA has released the first ever images of mysterious polar night clouds that form 50 miles above Earth’s surface, and says that they might be linked to global warming.
The startling images were captured by NASA’s “AIM” satellite (Aeronomy of Ice in the Mesosphere), and show night clouds above 70 degrees north latitude on May 25. Since then, eyewitnesses on the ground have reported seeing the formations on June 6 over Northern Europe (see image after the jump).
When viewed from space, the mysterious clouds are known scientifically as Polar Mesospheric Clouds, or PMCs, when seen from the ground they are called Noctilucent or “night-shining” Clouds.

We thought it might be fun to celebrate with some stunning photos of this planet we all live on!
Even if you’re not hitting up a local Earth Day event, you can still take today to celebrate. We hope these photos of the land and the critters who share it with us get you inspired!

“We often hear of environmental catastophes but almost never meet the people who suffer the consequences.”
Those are some of the introductory words of Lou Dematteis, one of the authors and photographers of the new photo book Crude Reflections: Oil, Ruin, and Resistance in the Amazon Rainforest.

If you’ve ever been to San Francisco, or lived there for a time as I have, you can’t help but be charmed by the city, but also aware of the natural beauty of the entire 9 county bay area. That charm and beauty, in many cases, was won in difficult and often contentious battles between environmentalists, governments and developers to name a few.
